Difference between XLPE and PVC Cables

Both Cables are widely used in Industries:PVC - stands for polyvinyl chloride XLPE - is cross linked polyethylene cable. Main Thumb rule for differentiation is that XLPE cables can be used for both HT and LT lines.But PVC Cables can be used only for LT lines.XLPE can withstand a higher temperature than PVC without detriment. This means that more current can be conducted for the same cross sectional area of copper. This means a big saving in cables costs.

1.Temperature resistance2. Stress rupture resistance 3. Environmental stress crack resistance 4. Resistance to U.V light5. Chemical resistance6. Oxidation resistanceXLPE Cables can be useful for following applications:- 1) XLPE cables work for the working voltage of 240 V to 500 KV . 2) Conductor Material can be either Copper or Aluminium. 3) XLPE cables can be either Single Core cables or Multi core cables depending upon the number of cores. 4) They can be Unarmoured or Strip Armoured or Wire Armoured or Tape Armoured type depending upon the presence or absence of Armour . 5) HT / LT Aerial Bunched Cables Polyvinyl chloride CablesThey are commonly abbreviated as PVC, insulated cables are widely used in various fields. PVC's Cables are generally have following Properties:-
